title: A minimally invasive technique for surgical treatment of hallux valgus: simple, effective, rapid, inexpensive (SERI).
abstract: OBJECTIVE
  Several bony and soft tissue procedures have been described for the treatment of hallux valgus, and currently mini-invasive surgical techniques are preferred in order to reduce surgical trauma, complications, time of surgery and to allow an earlier recovery. The aim of this study is to analyse a series of 1,000 consecutive cases of hallux valgus, surgically treated by the minimally invasive SERI technique, reporting results at mid-term follow-up.
  
  
  METHODS
  We prospectively studied 641 patients (1,000 feet) with symptomatic hallux valgus surgically treated by SERI osteotomy. Inclusion criteria were: age between 20 and 65 years, reducible mild or moderate hallux valgus, HVA ≤ 40°, IMA ≤ 20°, and arthritis of the first metatarsophalangeal joint up to grade 2 according to the Regnauld classification.
  
  
  RESULTS
  The American Orthopaedic Foot and Ankle Society (AOFAS) score rose from 46.8 ±  6.7 preoperatively to 89 ± 10.3 at last follow-up. Radiographic control at follow-up showed a complete healing of the osteotomy and remodelling of the metatarsal bone. Low rate of complication has been reported.
  
  
  CONCLUSIONS
  This study demonstrated that the SERI technique is effective in treating mild to moderate hallux valgus in terms of relief from symptoms and functional improvement. This technique allowed correction of the main parameters of the deformity, with durable clinical and radiographic results at a mid-term follow-up.
